INTRODUCTION: The aim of this investigation was to explore the validity of 3-dimensional (3D) spiral computed tomographic (CT) images to examine impacted teeth before surgical or orthodontic treatment.
METHODS: Two patients with impacted teeth were examined with both spiral CT and traditional radiographs.
RESULTS: 3D CT images clearly showed the impacted teeth, including crown, root neck, and root bifurcation; the labial or palatal location; and the eruption orientation and relationship to the dentition.
CONCLUSION: 3D CT images obtained with 3D surface reconstruction of spiral CT images is accurate and effective for examining impacted teeth before orthodontic treatment.
